Abstract: 260,087. Marrec, Ltd., and Anderson, A. Sept. 28, 1925. Harmonic telegraphs.-In a system of multiplex line telegraphy the signals are transmitted simultaneously on as many different low-frequencies having an order of difference of about 20 cycles, and the signals are separated at the receiving end 13 by selectively tuned circuits h1 - - h6, as described in Specification 225,867, [Class 40 (v), Wirelesssignalling &c. ] , after a common amplifier g. The circuits of each of the oscillation generators 1 - - 6 at the transmitting end A are opened between the signals by keys k1 - - k6 so that oscillation is quiescent when no signal is being sent. The oscillation generators are low-frequency oscillating valves v1, v2, v3 or buzzers z1, z2, z3, A multiple-wound transformer a may be dispensed with and the oscillations fed to an ordinary transformer through a plate circuit comprising a condenser, a tuned transformer, and a key. At the receiving end a filter may be used before the aperiodic amplifier and a common amplifier after the tuned amplifiers. The system may be applied to duplex signalling. Specifications 203,678.

Title: Method of and apparatus for airless fuel injection for internal combustion engines
IPC: F02M61/10
Filed: 1937-09-09
Abstract: 507,320. Fuel - injection pumps. BISCHOF, B. Sept. 9, 1937, No. 24604. Convention date, Sept. 9. 1936. Addition to 494,006, [Group XXVII]. [Class 102 (i)] [Also in Group XXVII] The method of fuel injection described in the parent Specification is modified by connecting the working chamber of the pump to a low-pressure chamber and, substantially at the same time, terminating the delivery into the injection conduit, and thereafter releasing the pressure in the injection conduit. As shown, the fuel is supplied by a pump, having a working chamber 14, past a non- return valve 63 into an injection conduit 19 leading to the space 26 below the injection valve 25. The chamber 14 also periodically communicates past a non-return valve 61 with a conduit 18 leading to the space 27 above the valve 25. Upward movement of the pump plunger 1. closes the suction passage 33 and the conduit 18 and delivers a preliminary charge of fuel past the valve 25 until an edge 55 on the plunger opens the conduit 18 to equalize the pressure in the spaces 14, 26 and to permit the springs 28, 62 to close the valves 27, 63. During further movement of the plunger the valve 63 opens and fuel is delivered simultaneously into the conduits 18, 19 until an edge 56 closes the conduit 18 ; continued movement of the plunger delivers the main fuel charge past the valve 25 until an inclined edge 57 opens a conduit 56 leading to a byepass chamber 59. The fall in pressure enables the spring 62 to close the valve 63 which is opened again by engagement with the face of the plunger to release the pressure in the conduit 19, and to enable the pressure in the space 27 to be released by opening a non-return valve 64. The quantity of fuel injected is regulated by rotating the plunger by a rack 9. In a modified construction the injection conduit is cut off from the working chamber by a valve controlled by the position. of the plunger.
